I would say it sucks for them. I guess that's what happens when you live in a majority rules democracy, and you end up on the side with less votes?

This is an incredibly ignorant statement. We live in a constitutional republic with democratically elected representatives. Those representatives are bound by the rule of law which forbids them from violating the rights of the minority, even if it is the will of the majority. The smoking ban is a clear violation of business owners' property rights.
